Top End Caps for Tap Relief Grinders

Abstract

The invention discloses a centre end cover of a screw tap relief grinding machine. The centre end cover of the screw tap relief grinding machine comprises a metal cover body and a round through hole, wherein the metal cover body is composed of a round metal base and a round metal ring in a connected mode, the round metal base and the round metal ring are placed in a front-and-rear mode, the round metal ring is arranged on the front portion, the round metal base is arranged on the rear portion, the round metal base is cylindrical, the round ring rear side of the round metal ring is connected with the round front side of the round metal base, the round through hole which is downwards drilled in the center of the circle of the round front side of the round metal base is a through hole, the round through hole, the round metal base and the round metal ring are concentric circles, round holes are downwards drilled in the round front side of the round metal base, are formed in three positions of the outer side of the round metal ring, and are through holes, the circumference formed by the centers of circles of the round holes in a connected mode, and the round through holes are concentric circles, the three round holes are evenly distributed in the round front side of the round metal base, the center of the circle of the uppermost round hole is arranged on the longitudinal middle line of the round metal base, turning is carried out on the circumferential edge of the round front side and the circumferential edge of the round rear side of the round metal base to form chamfers, and turning is carried out on the outer circumferential edge of the round ring front side of the round metal ring to form a chamfer.

Description

technical field [0001] The present invention relates to the top end cover of the tap relief grinder, specifically the top end cover of the relief grinder for cutting edge of the tap, which is a tool used on a numerically controlled machine tool. A new device for processing - an important part of the tap relief grinder. Background technique [0002] Usually, what must be used in machinery manufacturing and processing plants: one is the machine tool, and the other is the tools used on the machine tool. Both are indispensable. A good machine tool is like a CNC machine tool. The tools used are like taps, and the blade of the tap makes it sharp. To improve the quality of the tap, it is necessary to process and grind the tap, so that the blade of the tap is sharp, the quality of the tap is good, and the products produced are superior; and to achieve this goal, a relief grinder is needed to complete it; the existing Most of the shovel mills are imported and expensive; there are fe...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the defects of the top end cover of the common shovel grinder due to design errors and unreasonable structures, such as dislocation of the shovel grinder, low precision, and blade curling, etc., the present invention provides the top end cover of the tap shovel grinder. The top end cover of the tap shovel grinder is an important part of the shovel grinder. The design is correct and the structure is reasonable, which can make the shovel grinder work stably, ensure the work stability of the shovel grinder, and the edge of the tap produced by the shovel grinder is sharp , high precision, accurate relief grinding
